spring cloud微服务启动错误

今天在启动spring cloud微服务的时候，报了这个错误：

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.
2018-07-03 20:17:10.295 ERROR 19024 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter :

***************************
APPLICATION FAILED TO START

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Process finished with exit code 0

我的这个服务中没有用到数据库相关的东西，只是一个简单的restTemplate的消费者远程调用，结果启动时报错。以为是端口占用，但是换了端口号发现没用。然后在网上找了才知道springboot启动时会自动注入数据源和配置jpa。

解决方式：在springboot启动类的@SpringBootApplication后面加上(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})。

或者在application.yml中在配置一遍数据源。很难受，因此就第一种吧。。。
